Quantum Physics is the blanket term
Quantum mechanics is the math and the equations
Discovered by Max Planck in 1900
Then Einstein
Nils Bohr
Einstein branched off into relativity and disagrees with a random universe
Werner Heisenberg comes up with the Uncertainty Principle (1927)
Ernst Schrodinger continues
1950s
Everett proposes the many worlds ie. Multiverse theory
Carl Jung and Physicist Pauli explore human consciousness 30s to 50s Synchronicity
The 1990s
Quantum vibrations and physics are picked up by mysticists like Chopra
Penrose applies it to human consciousness, opposed by neuroscientists (1990s)
The 2000s
Quantum cognition and Quantum vibration terminology appears
Quantum computers
Theoretical 1980s, first machines built in 1990s
Proposed by Feynman
There are basically three main theories. Some are thought experiments like Schrodinger cat. These physicists have been debating who is right since the 1920s crossing into philosophy.
IBM and Google have them already. Housed in data centers. Highly sensitive. Huge data volumes are measured in qubits. Must be super cooled (almost absolute zero) and kept separate from normal environment. Prone to error and decohesion. Very slow compared to classic computers. Truly usable in about fifty years.
One example is taking all the data of a chaotic weather system and feeding them into it. It can calculate to predict the weather more accurately. But it does not actually "predict".
The movies and science fiction:
Avengers endgame was a great example of a multiverse and Quantum physics using magic and superpowers.
Other series were Asimovs foundation, Paradise and probably Devs. (Many others whose name I can't recall).
Quantum Physics is fascinating at the subatomic level but cannot be applied to a human life or the brain. Sorry?
A Quantum computer won't be able to predict anything ir examine past present future because we don't live in a predetermined universe that's set in stone.
Eg. If you mix all the ingredients to bake a cake you will get a cake. That's not prediction but a logical conclusion. A Quantum computer won't be able to predict that one outcome is that you burned it because you forgot to check on it. Not a prediction but a confirmation after the fact.
Unfortunately all the movies are great storytelling and a supercomputer that can tell us what will happen is an interesting story, but remains science fiction. We live in an indeterminate universe, random, chaotic that keeps reorganizing itself into a semblance of order. Almost all series/movies show us a deterministic universe; human lives have one path and all the choices keep us on that path.
Untrue because all the choices everyone else makes could interfere with that path. Free will basically.
There is a lot of hype around quantum computers. This is a good starting point.

ReplyDeleteBullet point summary of the basics.
I read an article yesterday, or maybe Friday, that the discovery of well defined old galaxies at the beginning of our universe confound the idea of the Big Bang, that the universe began at that point, that there was not enough time for them to have formed that early. So If I recall correctly, the idea is that they are remnants from the previous universe that expanded until it started to contract down to a single black hole, hit critical mass, and exploded, ejected all the material of our expanding universe. That our universe will eventually contract and create a new universe. I am, of course, paraphrasing simplistically.

DeleteMiscalculation. Nothing we can measure predates our universe. Those galaxies formed faster than was calculated so they are older than previously thought but not older than the big bang.
The big bang could be wrong as well. Basically physics at that level discover one piece of the four dimensional puzzle that is correct, but no one knows how it all fits together.
Hawking was hoping for a unified theory.
Right now lots of theories superstring believes that branes collided and so on.
IMO I don't think we're the only universe, so maybe it is cyclical. Who knows.

ReplyDeleteEllen did ya know Kip Thorne physicist did the mathematical equation Christopher Nolan produced the image (2014) followed by three scientific papers.
Then 2019 nasa confirmed that's what black holes look like.
